In this paper, the optimization problem of water depth measurement is studied. A new water depth measurement system is designed and implemented to solve the problem of poor real-time and large measurement error of water depth data in China. In the hardware design, using AT89C2051 and ultrasonic generator, a kind of ultrasonic sensor data acquisition and processing module which is suitable for complex pavement is designed, and the water depth information on the pavement is collected according to the principle of route difference and distance measurement. Problem, the use of temperature compensation and high efficiency filter module for de-noising water signal processing, the design of an improved LEACH energy balance routing algorithm to optimize the system to effectively reduce the node in the system death; system through GPRS wireless communication technology to Remote pavement control center to complete the water depth alarm; designed system to reduce the error of deep water measurement and improve real-time. The system test proves that the system can accurately and comprehensively measure the depth of water in different weather conditions and effectively overcome the interference. The energy consumption of the system is reduced by 5% and the optimization effect is obvious.
